The present study is planned to evaluate the efficacy of Resin Infiltration technique in improving the esthetics of non-pitted fluorosis stains on permanent anterior teeth. Resin infiltration is a novel method that has shown its efficacy in improving the esthetics of White spot lesions (WSLs) per say and post orthodontics WSLs in different both in-situ and in-vivo studies. The Resin Infiltration technique is also known to stop the progression of caries in non cavitated lesions in both, smooth surface and interproximal lesions.
